Well, finding out which articles are in a group basically means
querying the server and seeing what we get.  :-)

Gnus can't know in advance which articles exists on the server.
However, Gnus could keep track of which articles definitely aren't on
the server, so it could, say, keep a list of `dead' ranges of
articles that it knows aren't there, and then we could have a
function that does the complement of `gnus-active' and the `dead'
ranges.  That'll give us a better upper bound on how many articles
exist.

But I don't know how useful that would be.
